Modernising GWR

Along with our partners at Network Rail, we’re spending over £7.5 billion on electrification from London to Oxford, Swansea, Bristol and Newbury, station improvements and upgraded tracks to allow more frequent services.

The biggest fleet upgrade in a generation


From January 2017, we increased services of our brand new Electrostar trains to half hourly in each direction between Paddington and Hayes & Harlington. By the middle of 2017, as electrification of the Great Western Main Line progresses, services will operate as far as Maidenhead.

By the end of 2017, the first of our new Intercity Express fleet will start replacing our existing long distance trains across the network between London and Bristol, Bath, Swindon, Newbury and Reading.

Once Network Rail’s electrification work is completed, these trains will increase capacity by up to 25%, shorten journey times into London by up to 20 minutes, and allow us to run 54 more trains between London and Bristol every day.


From 2018, we’ll start upgrading trains running between London and Somerset, Devon and Cornwall. This will increase capacity by up to 25%, decrease journey times into and out of London and improve frequency.

Keeping you up to date

We’re working hard to keep disruption to a minimum, but we will need to change some of our planned services in the short term to make these improvements happen. For more information on what’s happening in your area, visit our Planned engineering page.
